The content of a Minerals Local Plan must meet the requirements of the National Planning Policy Framework (NPPF) and have regard to the content of the online national Planning Policy Guidance (PPG); both of which are discussed further in Section 2 below. One of the key aspects of a Minerals Local Plan is to plan for a steady and adequate supply of aggregates by identifying specific sites, preferred areas and/or areas of search. 1.2 LUC and Cuesta Consulting were appointed in December 2014 by HCC to review the Council’s previous mineral site selection methodology (developed in 2009), amend and update it where required, and then apply the methodology to identify suitable sites for the extraction of sand and gravel and brick clay in the county. In addition, a methodology for the identification of Minerals Safeguarding Areas (MSAs) and Minerals Consultation Areas (MCAs), and its subsequent implementation was required. 1.3 The conclusions and recommendations of this report will inform the emerging Minerals Local Plan (MLP), forming a key piece of its evidence base. Report Structure 1.4 This report includes a thorough review of national policy and guidance, together with national and local information which has informed the analysis and approach undertaken. It was critical that the site selection methodology meets the statutory local plan requirements: to be positively prepared, justified, effective and consistent with national policy and guidance. 1.5 The remainder of this report is structured as follows: • Chapter 2: National and local policy requirements relating to selecting sites for inclusion in MLPs and identifying MSAs and MCAs. • Chapter 3: Describes the site selection methodology for sand and gravel and brick clay. • Chapter 4: Describes the approach to brick clay. • Chapter 5: Describes the methodology for defining MSAs and MCAs and presents the proposed MSAs/MCAs. • Chapter 6: Sets out the findings of the sand and gravel and brick clay site and preferred area assessments. • Chapter 7: Study conclusions. 1.6 In addition, the Report contains two appendices: • Appendix 1: Completed Site Assessment Proforma. • Appendix 2: Hertfordshire Highways Department assessment of site options. 1 This is to ensure that the required landbank for sand and gravel can be met. As such, the total period for sand and gravel is 22 years. Hertfordshire Minerals Local Plan Site Selection Report 2 March 2017 2 Policy Requirements National Policy and Guidance 2.1 Minerals are essential to support economic growth and our quality of life. Paragraph 142 of the NPPF2 states that it is important that there is a sufficient supply of material to provide the infrastructure, buildings, energy and goods that the country needs, and emphasises that minerals can only be worked where they are found and it is important to make best use of them to secure their long-term conservation. This highlights the importance of the need to facilitate a steady and adequate supply of minerals, as required by the NPPF. Therefore a positively prepared, justified, effective approach to the site selection methodology and site selection study, which is consistent with national policy and guidance, is essential. Site Selection for Aggregates 2.2 The NPPF states in paragraph 145 that Minerals Planning Authorities (MPAs) should plan for a steady and adequate supply of aggregates by: • “…making provision for the land-won and other elements of their Local Aggregate Assessment in their mineral plans taking account of the advice of the Aggregate Working Parties and the National Aggregate Co-ordinating Group as appropriate. Such provision should take the form of specific sites, preferred areas and/or areas of search and locational criteria as appropriate; • …making provision for the maintenance of landbanks of at least 7 years for sand and gravel and at least 10 years for crushed rock, whilst ensuring that the capacity of operations to supply a wide range of materials is not compromised…;” 2.3 The online National Planning Practice Guidance3 (PPG) elaborates on the policies included in the NPPF, stating in paragraph 008 that MPAs should “plan for the steady and adequate supply of minerals in one or more of the following ways (in order of priority): • designating Specific Sites – where viable resources are known to exist, landowners are supportive of minerals development and the proposal is likely to be acceptable in planning terms. Such sites may also include essential operations associated with mineral extraction; • designating Preferred Areas, which are areas of known resources where planning permission might reasonably be anticipated. Such areas may also include essential operations associated with mineral extraction; and/or • designating Areas of Search – areas where knowledge of mineral resources may be less certain but within which planning permission may be granted, particularly if there is a potential shortfall in supply”. 2.4 In exceptional circumstances, such as where a MPA is largely made up of designated areas protection areas such as Areas of Outstanding Natural Beauty (AONBs), it may be appropriate to rely largely on policies which set out the general conditions against which applications will be assessed. However, it should be noted that HCC is not largely made up of designated sites/areas, and the main resource in the County, sand and gravel, is located outside the Chilterns AONB. 2.5 It is essential that when undertaking site selection that accurate and high quality data is used, as paragraph 009 of the PPG states that the better the quality of data available to MPAs, the better the prospect of a site being designated as a Specific Site.
